I was going to post but then I realized anyone who would get the joke already had, and anyone who wouldn't be familiar with Ikari wouldn't be familiar with Ayanami either.

FUN LEARNY TIME! LEARNING IS MANDATORY.

"Ikari" can mean a few different things depending on how it's spelled - Anger, Anchor, or three slightly different surnames that are pretty much pronounced the same. So there's probably a bit of symbolism in the names.
